Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.

ACRAcrosin heavy chain; Acrosin is the major protease of mammalian spermatozoa. It is a serine protease of trypsin-like cleavage specificity, it is synthesized in a zymogen form, proacrosin and stored in the acrosome. (421 aa)    
Predicted Functional Partners:
ACRBP
Acrosin-binding protein; May be involved in packaging and condensation of the acrosin zymogen in the acrosomal matrix via its association with proacrosin.
   
  
 0.913
ZPBP
Zona pellucida-binding protein 1; Plays a role in acrosome compaction and sperm morphogenesis. Is implicated in sperm-oocyte interaction during fertilization (By similarity).
   
  
 0.857
IZUMO1
Izumo sperm-egg fusion protein 1; Essential sperm cell-surface protein required for fertilization by acting as a ligand for IZUMO1R/JUNO receptor on egg. The IZUMO1:IZUMO1R/JUNO interaction is a necessary adhesion event between sperm and egg that is required for fertilization but is not sufficient for cell fusion. The ligand- receptor interaction probably does not act as a membrane 'fusogen'.
   
 
 0.823
AKAP3
A-kinase anchor protein 3; May function as a regulator of both motility- and head- associated functions such as capacitation and the acrosome reaction.
   
  
 0.821
AKAP4
A-kinase anchor protein 4; Major structural component of sperm fibrous sheath. Plays a role in sperm motility; Belongs to the AKAP110 family.
   
  
 0.811
IZUMO4
Izumo sperm-egg fusion protein 4; IZUMO family member 4; Belongs to the Izumo family.
   
 
 0.776
SPACA1
Sperm acrosome membrane-associated protein 1; Plays a role in acrosome expansion and establishment of normal sperm morphology during spermatogenesis (By similarity). Important for male fertility.
   
  
 0.772
CCIN
Calicin; Possible morphogenetic cytoskeletal element in spermiogenic differentiation.
   
  
 0.728
ZP2
Processed zona pellucida sperm-binding protein 2; Component of the zona pellucida, an extracellular matrix surrounding oocytes which mediates sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy. The zona pellucida is composed of 3 to 4 glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP2 may act as a secondary sperm receptor.
   
 
 0.728
ZP3
Processed zona pellucida sperm-binding protein 3; Component of the zona pellucida, an extracellular matrix surrounding oocytes which mediates sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy. The zona pellucida is composed of 3 to 4 glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP3 is essential for sperm binding and zona matrix formation.
